Heidi Klum made quite an impression today in NYC as she showed off her model figure and killer smile at the Empire State Building lighting ceremony honoring bone-marrow donors.
The model is shining a light on DKMS, the largest bone-marrow donor center in the world and helps save many lives each year in the fight against blood cancer.
Heidi Tweeted this afternoon, "What a beautiful view of New York City from the top of the Empire State Building!!" adding, "Lighting the Empire State Building red in honor of DKMS. #FightBloodCancer."
